ELECTRIC CATCHER AND CONVEYER.

Application filed December 4, 1923. Serial No. 678,410.

To all whom it may concern:

Be it known that I, WILLIAM A. F rrz- SIMMONS, a citizen of the UnitedStates, residing at Canton, in the county of Stark and State of Ohio,have invented certain new and useful Improvements in Electric Catchersand Conveyers, of which the following is a specification.

This invention relates to mechanism for catching sheets of steel and thelike as they emerge from cold rolls, shears, bucklers, presses, stampingmachines, and other machines through which cold sheets are passed; andfor conveying the sheets away from the nilachine and depositing themin'any desired ace.

The objects of the improvement are to provide a machine of thischaracter having an endless belt carrying electro-magnets arranged tocatch each sheet as it emerges from the cold rolls or other machine andcarry the sheet away from the machine and deposit it at a suitable placeaway from the machine.

Although the improved catcher and conveyer may be applied to numeroussheet handling machines, for the purpose of illustration it is shownapplied to a cold rolling mill in the accompanying drawings, in wh1ch-Figure 1 is a side'elevation of the electric catcher and conveyerattached to a cold rollig 2, a fragmentary plan view of'a por tion ofthe endless belt which carries the ma nets;

igs. 3 and 4, detail views of the pulleys over which the belt travels;and I Fig. 5, a section on the line 5-5, Fig. 1.

Similar numerals refer to. similar parts throughout the drawings.

A portion of the housing of a cold rolling mill is shown at 1 and. therolls thereof at 2, the usual table 3 being located in position toreceive the sheets upon the fiber rollers 4, as they emerge from therolls of the mill.

The improved catcher is mounted in a frame comprising the side members 5con nected to ether in suitable manner and. provided wit the notches 6at one end for engagement with the rest bar 7 of the mill, the other endbeing preferably provided with uprights 8 to which are connected suspension braces 9, which may be attached to the housings of the mill.

A platform 10 is supported upon the side members 5 and carries a motor11 having a pinion 12 upon its shaft meshing with a gear 13 upon acountershaft 14. A sprocket 15 is fixed upon the shaft 14 and connectedby the sprocket chain 16 with a similar sprocket 17 fixed upon the shaft18 of the pulley 19.

This pulley is preferably provided with an' insulated periphery andcarries a conductor ring 20 near one side thereof. A similar ulley 21 islocated at the forward end of t e frame and provided with a conductorring 22 located near the other side, an endless belt 23 being locatedaround said pulleys and provided with the woven wire conductors 24 and25, arranged to engage the conductor rings 20 and 22 respectively.

Electro-magnets 26 are connected at close intervals to the belt 23, eachmagnet being connected to both of the conductors 24 and 25. A brush 27,connected to one side of an electric circuit, is permanently held incontact with the conductor ring 22 upon the pulley 21.

A brush 28 is mounted for slidable movement upon the frame and connectedby a link 29 with the upper end of a lever 30 pivoted intermediate itsends as at 31 to the frame, and arranged. to normally-hang in thevertical position, as shown in Fig. 1, holding the brush 28 out ofcontact with the conductor ring 20 of the pulley 19.

A fiber roller 32 is journaled upon the lower end portion of the lever30 in the path of sheets emerging from the rolls of the mill.

As the forward end of each sheet passes over the rollers 4 upon thetable 3 and contacts with the'fiber roller 32.upon the lever 30, thelever will be tilted by the sheet, permitting the same to pass under theroller 32, this tilting of the'lever moving the brush 28 into contactwith the conductor 20 back to its normal position, disengaging the brush28 from the conductor ring 20, breaking the circuit through theconductors 24 desired point where the magnets are automaticallydeenergized by the sheet passing out of engagement with the fiber rollerupon the lever 30, thus obviating the necessity of providing an operatorfor the catcher and oonveyer.

I claim 1. A. catcher and conveyor for receiving moving sheets,including an endless belt, magnets upon .the belt adapted to attract thesheets, and means operated by the movement of the sheet forailtomatically energizing the magnets.

2. A catcher and eonveyer for receiving moving sheets, including anendless belt, magnets upon the belt adapted to attract the sheets, andmeans operated by the movement of the sheet for automatically energizingthe magnets at a predeterminedpoint and deenergizing the magnets at apredetermined point.

rename electro-magnets upon the belt, a movable brush for closing thecircuit to said mag= nets, a pivoted lever operatively connected to thebrush and located in the path of the sheets, and a fiber roller uponsaid lever for engagement with the sheets.

5. A catcher and conveyer for receiving moving sheets, including anendless belt having two endless conductors mounted therein, ulleys overwhich the endless belt is located a conductor ring upon each pulleyengaging one of the conductors in the belt, a brush permanently en aginone conductor ring, a brush norma 1y he d out of engagement with theother ring, electromagnets upon the belt connected to the conductors andmeans operated by the movement of a sheet for automatically engaging thelast named brush with the adjacent con- In testimony that I claim theabove, I have hereunto subscribed my name.
